My breastfeeding journey is about to end 😪

My baby is two weeks old. In the beginning he had a bad latch and my nipples were destroyed. I was advised by my LC to pump and let them heal. Then my baby's latch improved so my LC advised me to gradually increase how often I bring him to breast. When I went back to mostly breastfeeding he would eat for 45 mins, sleep for 30 mins, eat again for 45, etc. This went on for two days so I called his pediatrician who said he wasn't getting full from my breasts and I should breastfeed for 30 mins, then bottle feed pumped milk, supplement with formula if necessary, then pump. This is too exhausting for me and I'm suffering from severe postpartum depression from all the stress. I hallucinate every time I wake up. I get dizzy when I pump. Ive have severe crying spells every few hours since the day he was born. I started pumping less and supplementing with formula yesterday and he finally sleeps for 2-3 hours at a time now. My poor baby was starving. I physically and emotionally can't keep trying to breastfeed and it makes me feel incredibly guilty.
